A wave of COVID-19 related PTSD? Disentangling the impact of exposure to COVID-19 related events on probable posttraumatic stress disorder in the general Dutch population

Abstract

Introduction

The COVID-19 pandemic highlighted a critical gap in our knowledge on the impact on mental health, especially trauma-related disorders like PTSD. With future pandemics anticipated due to global health risks, it is essential to rigorously study the prevalence of PTSD resulting from COVID-19. Such research will help us understand the psychological effects of pandemics and develop better strategies for mental health support in future crises.

Methods

This study uses data from the Dutch Public Health Monitor Adults and Elderly 2022, consisting of 365,000 Dutch adults recruited using random sampling. Pandemic-related and non-COVID related potentially traumatic events were assessed and anchored to a validated screening instrument for PTSD, the Dutch version of the PCL-5.

Results

Two-thirds of participants reported experiencing traumatic events during the pandemic. Exposure to pandemic-related traumatic events was reported more frequently than non-COVID related traumatic events. Overall probable PTSD prevalence due to these events was 2.4%, evenly split between pandemic-related and non-COVID related traumatic events. Among exposed individuals, probable PTSD prevalence was 3.7%. The risk was higher for exposure to non-COVID related events such as sexual violence, physical violence and life-threatening accidents than exposure to pandemic-related traumatic events like hospitalization or death of someone significant. Risk factors for developing probable PTSD after exposure to a traumatic event during the pandemic were younger age, financial difficulties, loneliness, low resilience, and experiencing multiple events.

Discussion

Exposure to traumatic events during the pandemic influenced the prevalence of probable PTSD. Despite the lower relative impact of pandemic-related traumatic events compared to non-COVID related traumatic events, exposure to pandemic-related traumatic events accounted for 1.1% of probable PTSD in the population and is thereby comparable in impact to five commonly occurring traumatic events. This emphasizes the need to address mental health consequences and risk factors during pandemics and, potentially, other crises with population-wide exposure to events.
